Stage 3 M156 Supercharger System

The Weistec Stage 3 M156 Supercharger System is engineered to dramatically increase the performance of M156 engine families. This system utilizes a robust 3.0L Twin Screw Compressor and is configured with a 12 PSI pulley for enhanced power output. This supercharger system provides substantial performance enhancements. According to available data, it can achieve horsepower figures between 637 and 672 WHP, with torque outputs ranging from 560 to 662 ft-lb. These gains represent a significant increase over the stock M156 engine's 451 horsepower rating. Installation of the Stage 3 Supercharger System requires specific modifications to ensure optimal performance and compatibility. These requirements include the installation of a high-flow exhaust system, the removal of secondary air injection valves, the use of ROW airboxes, and replacement spark plugs. It is also noted that a built transmission is recommended for handling the increased power. This supercharger system is compatible with various AMG M156 equipped vehicles, including the SL63, R63, ML63, CLS63, CL63, CLK63, S63, E63, and C63 AMG models. While the specific model year range is not explicitly detailed for all applications, the system is designed for the M156 engine family.
